- The invention relates to a mixingl chamber or fluid mixing device for mixing any desired'fluid medicine or the like with a stream of water from a faucet. Y Y

An object of the invention is to by-Dass the water from the faucet-without diluting the liq- Another object of the invention is to provideV a device of the character'v described of moldable material-such as plastic. l

YAnother object of the-invention is to provide a mixingichamber adapted to be mounted on and: supported by the faucet spout. A

For further. details 'ofthe invention referenc may beimade to the drawing, wherein: Y

Figure 1 is a vertical sectional viewfoi a mixing .chamber or device according to the present invention;

Fig. 2 is a sectional view onl line 2-2 of Fig. 1, looking in the directionA of the arrows.

,-Figs. 3 andfi are views in side elevation and plan, respectively, of the toggley ofV Fig. 1 for clamping the device of Fig. 1 to aV faucet spout,

notshown.

vReferring in-detail to the drawing, the mixing chamber or device of this invention comprises acontainer I having a cap` 2 in which is mounted a transverse conduit fitting 3. The conduit htting 3 comprises two telescoping sections of which the section 4 passes through an aperture `5 in the side wall 6 of the cap 2, vthe section 4 terminating at its outlet end ina stop flange 60 vand in corrugations 1 forming a connection for a. hose 8. The hose 8 has va conventional clamp vor shut-off valve, notV shown. Fittingin the "pipe section 4 is an aligned section 9 having at lits outer end an enlarged bore I .in which is arranged a compression spring II which bears tion 9 terminates'ina ilange' I5 which serves as a wallportion which supplements and t's o'nI the complementary wall portion I6 of the container I.. Theflange Vor wall portion I at its opposite sides vvand topA ts in a groove. I1 in the lcan2....,.'1711esidewall I 6 44of the container Iphas s claims. (ci. 2994-84) Z an outwardly extending flange I8 and the flange I8 and the topl of container I removably intert as indicated .by the intertting portionsl I9. Thebore I0 at its left end opens into the space between the wall I2 and the flange 'I5 and the latter space in turn, opens into the spacebetween the wall I6 and the ange vIll to provide a relief outlet indicated at 20.

Depending from the conduit section annular ilange 2l in which is fitted a suction tube nozzle 22 having an outlet` 23-which `projects into 'the' conduit section -9 and faces outwardlyV is pressure in the suction tube 24. l Valve 26 V opens to admit fluid indicated at 32 from the container I into the tube 24 when water vfrom the faucet,ynotv shown, is Vflowing throughthe transverse conduit section 9 to the'mixed fluid outlet 4. 1 Y

Arising from the conduit section 9,'b'etween the suction outlet 23 and the relief valve I3 is a sleeve 33 which servesfas aninlet'and is v provided with internal screw threads 34.

Threaded into the threads 34 is a hollow` num-f ble 35 having at its upper end a flange 36 which Ato overlies an inwardly-projecting flange 31 on a rubber sleeve washer 38. The Washer flange 31 fits on an inlturned flange 39 at the base` of the neck 40 of the .cap 2. yThe washer flange 31 is clamped on the neck flange 39, between the thimble flange 36 andthe said flange 39, to prevent leakage at that place, and to preventthe sleeve washer 33` from blowing out when the device is inuse. j

The means herein disclosed for clamping lthe mixing device I2,`to the spout of Va. faucet,`not shown, is described and claimed in my 'copending application,` Serial No.. 58,2,673,iiled March 14, ,1945, for `Faucet attachment, and-here is 'shown as comprising* aj compressible neck-49 vwhich arises from and is integral with the cap 2 and provided with a number ofY longitudinal slots 4I ,here indicatedA as fourinfnumber, whereby theneck 40 being; of plastic material is compressible. -Around the neck 4u-is arranged a clamping han@ 42 ,hevige ,e i955?? 52.55" that.

9 is-'anv the neck 4i) can be kclamped or unc'lamped from the faucet spout.

hose 8, sleeve washer 38 and clamping band 42 n and toggle 43, may be cast of mo'ldable material.

such as plastic which is slightly flexible when `in the form of a hollow container and cap as indichamber having therein a transverse conduit of which one end is a relief outlet and the other end a mixed fluid outlet, a spring pressed relief valve closing said relief outlet, a suction tube depending from said conduit between said outlets, a check Valve opening to suction and closing to prevent reverse ilow for said suction tube, said suctionV tube having in said conduit an outlet facing said mixed fluidoutlet, and a fluid inlet opening into 'said conduit between said suction tube outlet and said relief Valve, said parts being constructed and cated at I, 2. Accordingly, the opposite side walls 41, 41a as indicated in Fig. 2, may be pressed yinwardly at their .top to release the grooves 48, 49 from theribs 50 and 5I at the lower edgesofthe cap 2, to remove container I from cap 2 while the latter is clamped on the faucet. grooves 48 to 5I need not extend the full width of the container I and are illustrated in Fig. 1 as extending approximately yl/i of the width ofthe container, as indicatedat `52. The side walls of container I may bethickened for the length of the grooves 48, 49 ,as shown at 6I, 62. The container'I and cap 2 at their meeting edges I9 are somewhat rectangular in cross section, whereby the opposite side walls 4'I and 48 and the corn-y panion side Walls on the cap'f2 are substantially ilat.`

The ribs' and In assembling the .device the check vaivezslis Y mounted in the lower end of tube `24 and the cap 25 is cementedV or fused in theposition shown, with a plastic Isolvent.Y The tube 24 with the suction nozzle 22T above it, are cemented in the sleeve 2I. The conduit section 9, after placing therelief valve I3 and spring II in place, is mounted in the cap, with'ilange'` I5 fitted in the recess I7. Then the conduit section 4 isf passed, through the opening 5` from rightto left, and telescoped in and cemented ,to` the conduit section 9. The sleeve 38 is lltted in the neck .-40 and clamped `inposition bythe thimble 35.V Thus, thereis mounted in the cap 2 a T shaped integral fitting wherein one branch is the relief passage Ill, the other branch the mixed fluid outlet 4, the stem being the suction tube 24, *withr an inlet sleeve 33 arising from section 3 between relief valve rI and suction tube 24. The device is then .ready for use as above described, and when the toggle 43 isl employed to clamp the neck v4I) and the washer 38 to the faucet spout, the latter` will support the mixing device I, 2.

A particular advantage ofabove described is that after the operator places a desired amount of medicine or other fluid 32 in the container I, and fits it onto the cap 2 which is assumed to be clamped on the faucet spout, the operator may then close off the hose 8, turn on the faucet Aand adjust the relative amounts of hot and cold Water, and its volume, While such waterl is by-passed through the relief valve I3 and relief outlet without entering container I or picking up any of the fluid 32. When'the operator desires to discharge through the hose V8 a vmixture of .the Iwater from the faucet andthe fluid 32, it is simply necessary to open the valve,

*the construction4 flange and said inlet branch arranged so that iluid from said inlet can dis.

charge through said relief outlet and not through said suction tube into said chamber when saidY fluid outlet when the latter is open.

2. VA fluid mixing device having a container and a cap therefor, said cap having a conduit fitting therethrough, one end of said conduit iltting being a mixed fluid outlet and the other end of said passage ,being a relief outlet to the outside of said container, a relief valve for said relief outlet, a suction tube having an inlet in its lower end and an outlet in said conduit tting, and a faucetV connection having an inlet -conduit openingl into said conduit fitting onthe side of said suction outletopposite said mixed;` fluid outlet and between said suction outlet and said relief outlet. -y v 3. A fluid mixing device according to claim 2 wherein said` container has a wall, one portion Y having an inletarisingfrom one branchof said T, the outer end of Which'terminates in a relief passage leading to the outside of said container, a relief Valve therefor, the outer end of another branch being a mixed: iluid outlet, andthe-.stem

of said T .being a suction tube for said container,

meansfor supporting theroutlet branchesof said 'T Yon theiopposite wallsV offsaidcap and. means for supporting said inlet in said' neck.`
